Abstract:

This study summarizes the results obtained from measurements of the exchange rates of N2O–N, NO–N, NO2–N and CH4 between Scots pine forest soils of the northeastern German lowlands and the atmosphere in the years 1995–1998. In order to further identify the effects of atmospheric N-deposition on the magnitude of N- and C-trace gas fluxes, five Scots pine forest sites with different loads of atmospheric N-input (15–22 kg N ha1 per year) were investigated. The measurements show an increase in NO and N2O fluxes at the higher N-affected sites (mean values, NO: 21–39 μg NO–N m2 h1, N2O: 16–32 μg N2O–N m2 h1) as compared to the sites with moderate atmospheric N-input (mean values, NO: 3–9 μg NO–N m2 h1, N2O: 5–10 μg N2O–N m2 h1). ... mehr
